RAIL.

Specification of Letters Patent.

Patented Oct. 19, 1909.

Application filed September 2l, 1908. Serial No. 453,902.

To all lwhom 'it may concern: j

' Be it known that I, PETER PETERSON, a 1 citizen of the United States, residing at Gulliver, in the county of Schoolcraft and State of Michigan, have invented4 certain new and useful Improvements in Rails, of which the following is a specification.

This invention relates to railways, and more particularly to rails, and has for its object to provide a compound rail having a tread portion adapted to replacement without disturbing the flange and lower web portions of the rail.

Another object of the invention is to provide a tread portion adapted to engagement with the base portion of the rail to be held thereon without the use of complicated fastening means, and in case of emergency may be secured in place with any suitabley form of spike, bar, or even a wooden pin.

Another object is to provide a tread portion adapted to be secured upon the base portion by the use of but one fastening member, both ends of each tread section being thereby held securely against the base portion.

A further object of this invention is to provide means for securing the ends of adjacent base portions in rigid coengagement against relative displacement vertically.

A still further object of the invention is to provide an effective means for bracing the web portion of the base against lateral displacement.

Other objects and advantages will be apparent from the following description and it will be understood that changes in the specific structure shown and described may be made within the scope of the claims, and that any suitable materials may be used without departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a side view of a base section and portions of tread sections enl gaged therewith, Fig. 2 is a longitudinal section of a similar section of track, Fig. 3 l is a cross sectional view of the rail adjacent to the end of the base section, Fig. 4t is a l similar view adjacent to the end of the tread section, showing the securing means. j

Referring to the drawings, there is shown l a rail comprising a base portion 10 having a l.

longitudinally bifurcated or slotted web p0rtion 11 and opposite brace portions 12 outwardly thereof at spaced intervals and eX- tending diagonally upward from the adjacent flange portion 14 to engage beneath an outwardly offset rib 15 formed at the upper edge of the web 11. The opposite ends of the base section have openings formed through the opposite flanges and are disposed over base plates 17 having similarly spaced openings therein. Bolts 18 are engaged through the openings in the flanges and base plate and have nuts secured thereover to clamp the base section 10 securely to the plate to prevent vibration thereof. In use, a tie should be disposed beneath the base plate, being depressed somewhat below the level of adjacent ties to compensate for the thickness of the plate 17.

Engaged upon .the base portion 10 there is a detachable tread portion 2O having a tread of the usual shape and provided with a depending flange or web portion 21 adapted for close engagement in the slot 11. It will be noted that the sides of the portion 21 join the tread portion at a slightly obtuse angle, the tread portion extending outwardly approximately in a horizontal plane. It will be noted that the top portions of the web 10 on opposite sides of the slot 11 are as nearly level as possible and the communicating wall portions of the slots converge slightlyV at their bases. From this it will be apparent that the tread portion may be easily placed in position and will be firmly supported, and by the use of the braces 12 there will be no tendency of the web 11 to spread. One end of the flange 21 projects outwardly beyond the adjacent end of the tread 20, the outer end edge being inclined upwardly and inwardly from its base to its junction with the tread. The opposite end edge of the flange is inclined inwardly from its junction with the tread, and adapted to engage over the projecting portion of an adjacent tread section when disposed upon the base portion A. rlhe inwardly sloped ends of the flange 21 are each provided with a pendent tenon portion 23 adapted to engage loosely in a similarly formed recess in the base of the slot 11 centrally of the base portion 10. A rectangular opening 24 is formed through the tenon and in the web portion 11, centrally of the base, there are formed registering openings 25 adapted to register with the openings 24 when the tread is disposed upon the base. A suitable fastening member 26 is engaged through the openings 24 and 25 to hold the tread portion in firm engagev ment with the base.

In operation, the bases are disposed upon the ties and secured by suitable spikes' or other means, the foundation plates 17 being gaged beneath the inwardly inclined portions as shown. In this manner, the fastened end of one rail serves to secure the opposite end of an adjacent rail to the base section. It will be seen that in the event that the tread becomes worn upon this form of rail it may be removed and a new one replaced ata minimum expense of time and labor. The expense of providing an entire new rail on account of the defectiveness or wear ofthe small portion comprising the tread is thus obviated.

What is claimed is: j

-l. A rail comprising a base portion having av longitudinally slotted web, said slot having a recessed portion cent-rally thereof, and a tread portion having a depending web portion adapted to engage removably in the slotted web of the base section, the web of the tread portion being inclined outwardly and downwardly from its junction with the tread portion at one end and being inclined inwardly and downwardly at its other end to receive the outwardly inclined portion of a similar web portion thereunder, and means for securing said tread portion to .the base section. Y

2. A compound rail comprising a base portion having a longitudinally slotted web portion, said web portion having registering openings formed therethrough, said slot having a recess centrally thereof below said registering openings, a tread portion having a pendent web portion adapted to be detachably engaged in saidslotted web, said pendjecting web portion of an adjacent `tread Y section, said pendent portion having an opening therethrough adapted to register with lsaid openings through the first named web when said sections are in operative position, and means for securing said tread portion to the base section.

In testimony whereof I affix my signature, in presence ofvtwo witnesses.
